Many travelers now use review sites on the web to pick accodations, transport, and so forth when planning trips. They have caused a lot of discussion over the years, for example: Is Trip Advisor paying for bad reviews?

A study of a news review site released today by MIT found a herd effect among reviewers leading to inflated positive reviews. Basically, people tend to rate positively items that are already positively rated. The Guardian has a story on it:

What effect, if any, will this have on such sites, and Travelbloggers use of them? Reply to this

I guess that is true as i do look at the top 10 or so of accomodation in a city on different sites, so even me just reviewing them myself is a bias as i have already filtered what i'm looking at.

I think we just have to look for constructive information in reviews and try to ignore any that are positive or negative and i guess from the above, be aware that there might be perfectly reasonable and fantastic accomodation further down the lists regardless of the number or types of reviews it has received 😊 Reply to this
